A day before the comeback, DKB announced the imminent comeback by releasing the last version of the music video teaser unit of the new song "ALL IN".

Brave Entertainment, its agency, unveiled the last version of the music video unit version of the title song "ALL IN" of its first full-length album "The dice is cast" on DKB's official SNS channel at midnight today.

In the teaser video released, members Lee Chan, Yuku, and Harry Jun appeared.

They drew attention by expressing their sad and sad feelings through the antique and vintage restaurant, the smoke of sweeping away objects on the table, grabbing the tablecloth tightly, and the acting of suffering from their faces wrapped around them.
